DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 507,889, dated October31, 1893.

Application filed August 31, 1893. Serial No. 484,430- (No model.)

To all whom it may concern:

Be it known that I, TERTULLUS S. DIBLIN, a citizen of the United States,residing at Trenton, in the county of Mercer and State of New Jersey,have invented certain new and useful Improvements in Door-Checks, ofwhich the following is a specification.

This invention relates to door checks, and its novelty will be fullyunderstood-from the following description and claim when taken inconnection with the annexed drawings; and the object of the invention isto provide a door v check of simple, durable and inexpensiveconstruction, to effect holding a door open or closed or partly so,through the friction of an elastic cushion or rubber ball in contactwiththe floor of a dwelling houe,or other build- 1ng.

Theinvention consists in the novel arrangement and construction ofparts, as will be hereinafter more fully described and set up in theclaim.

In the accompanying drawings forming part of this application: Figure 1is a perspective view of a portion ofa building showing a door providedwith my improved check. Fig. 2 is an enlarged front view of the doorcheck. Fig. 3 is a side elevation thereof. Fig. 4 is a sectional viewtaken on the plane indicated by the dotted line 0ca3 in Fig. 2.

The same letters of reference denote the same parts throughout theseveral figures.

To the doorA, is secured by screws a, the bracket 13, having two rightangle loop projections C, and D, respectively, formed integral with thebracket B. The loop projection G, has teeth 0, formed upon its end, uponthe inside. Through these loops 0, and D, extends a slidable lever E. Tothe lower end of this lever E, is secured a cushion or rubber bail F, bymeans of a pin f, passing'part way or entirely through the said cushionor ball, and through the said end of the lever E. A rack or teeth e, isformed upon the lever E, above its central portion, which engages theteeth c, of the loop projection 0. Midway between the cushion F, and thelower ends of the teeth e, is secured to the back of the lever E, theplate spring G, for keeping the two sets of teeth engaged, except whenthe lever E, is being raised or lowered.

The upper end of the lever E, is curled both towards the front and back,from the central vertical plane of said lever, to form thumb and fingerhandles H, and '11, respectively, and when this handle is pushed by thethumb it causes the said sets of teeth 0, and

e, to disengage, leaving the lever E, free to be raised or lowered bythe fingers of the same hand of which the thumb upon the said han die isa member;

It is believed the principle of operation of this check is so well knownthat it will not be set out further herein. The connection between thelever and the cushion is of great advantage, owing to its simplicity andeffectiveness. The construction of the hand portion of the lever enablesit to be operated with one hand with the greatest of ease and accuracy.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a door check, the bracket, the toothed loop formed integral with thebracket, the slidable lever having teeth, the plate spring bearingagainst the bracket and secured to the lever, and normally keeping theteeth of the lever engaged with the said toothed loop, the cushion ball,means forsecuringit to one end of the lever, and the thumb and fingerhandle formed upon the other end of the said lever, substantially asshown and described and for the purpose set forth.

In witness whereof I hereunto set my hand in the presence of twoWitnesses.

TERTULLUS S. DIBLIN.
